Django Rest Framework - common nested serializer for multiple models with the same base class
Assuming that we have the following models: from django.db import models class BaseModel(models.Model): field_a = models.TextField() field_b = models.IntegerField() class Meta: abstract = True class ModelA(BaseModel): some_relation = models.ForeignKey( "app.RelatedModelA", related_name="model_a_set", ... ) class ModelB(BaseModel): different_relation = models.ForeignKey( "app.RelatedModelB", related_name="model_b_set", ... ) class RelatedModelA(models.Model): pass class RelatedModelB(models.Model): pass I would like to be able to define serializers in the following way: from rest_framework import serializers class RelatedModelASerializer(serializers.ModelSerializer): model_a_set = BaseModelSerializer(many=True) class Meta: model = RelatedModelA fields = ("id", "model_a_set") class RelatedModelBSerializer(serializers.ModelSerializer): model_b_set = BaseModelSerializer(many=True) class Meta: model = RelatedModelB fields = ("id", "model_b_set") The question is - how to define BaseModelSerializer? I found a solution that takes into account overriding to_representation, although it requires writing serializers for each type separately (ModelASerializer and ModelBSerializer), so it would look like this: class BaseModelSerializer(serializers.ModelSerializer): def to_representation(self, obj): if isinstance(obj, ModelA): return ModelASerializer(obj, context=self.context).to_representation(obj) elif isinstance(obj, ModelB): return ModelBSerializer(obj, context=self.context).to_representation(obj) raise NotImplementedError class Meta: model = BaseModel fields = ("id", "field_a", "field_b") The ideal solution for me would be something like that, without defining serializers for ModelA and ModelB: class BaseModelSerializer(serializers.ModelSerializer): class Meta: model = BaseModel fields = ("id", "field_a", "field_b") but unfortunately it won't work that way, because an abstract model cannot be … -
How to create a django model record using get_or_create and select_related
I have a class like below: class GroupProduct(models.Model): product = models.ForeignKey( 'myapp.Products' related_name='myapp_group_product') @classmethod def create_group_product(cls, p_id, product_id): cls.objects.get_or_create(id=p_id, defaults=dict(product=product_id).select_related('product') So I expect it creates a record in the table with the following params, however it doesn't. GP = GroupProduct() GP.create_group_product(3, 225) It says it product must be a myapp.Products instance. Is there any way to use select_related in this way rather than doing a seprate query and hit the database? -
Mapboxgl breaks when I change django language in settings
Basically my code works well when language in django settings.py is set to "en-us" But when I try to change it I get: Uncaught Error: Invalid LngLat object: (NaN, NaN) at new Ha (lng_lat.js:39:19) at Function.convert (lng_lat.js:142:20) at Rr.setLngLat (marker.js:337:31) at dodaj_marker ((indeks):282:37) at (indeks):296:9 I'm changing lang because I need to get months in different language, but how does it affect mapbox? Is there any mapbox language variable I have to edit in order to get it working ? -

How to fill in programmatically Django admin built-in autocomplete?
I would like to use JS in the Django admin to fill in programmatically a field that uses the built-in autocomplete option (NOT autocomplete-light). Let's say the field is called myfavfield. I can retrieve it with JS as follows $("#id_myfavfield"). If it is already filled in with some values, I can retrieve them with $("#id_myfavfield").val();, which, for example, returns ['1', '4'], I can also clear myfavfield with $("#id_myfavfield").empty();. However, I can't fill it in, for example, by running $("#id_myfavfield").val(['2', '4', '5']); or any other way that I have tried. Does anybody know how one can achieve that? -
Django - display image from database in edit form
I recorded a form that also contained an image. I would like that later in edit form to be able to visually see the previously uploaded image before changing it. I tried to display it in edit form via <img src = "{{curs.poster_curs.url}}" alt = "alternate text"> but in inspect it shows src = "unknown". How can I display the image already uploaded in edit form? I ask for a solution in this regard. Thank you -
Post a dcitionaries and lists along with a file using python resquests
I built an endpoint using Django-rest-framework which expects a file and some other information, including some dictionaries and lists. If I make the request using the browsable API from drf, none of the data is truncated and I also receive the file. However if I make a POST request through Python-requests library it doesn't work and the data received on the server side is received truncated as HTTP form-encoding is not capable of representing nested data structures. Does anyone know how can I reproduce the same behavior as the browsable API in the request through python requests library and avoid the truncation? Any help is greatly appreciated. -
django-tenants: redirecting to tenant url after login raises "NoReverseMatch: 'demo.localhost' is not a registered namespace"
I don't seem to find a way to solve an error happening at the user authentication. User needs to login at the public website level let's say localhost/login and when he/she is authenticated, I need the user to be redirected in the corresponding sub domain, for example demo.localhost. This is not working for me so far, even after checking some posts about the subject.

Django ORM count or get precentage report
I have three models named Category, Account, and AccountCategory. I need to be able to generate a report wherein I can show the number of which each account was categorized. (e.g let's say I have 10 accounts, then I have three categories (A, B, C) I need to be able to show a piechart) Account has a many-to-many relationship with Category and AccountCategory is the junction table. Ideally, I need to have a result of Name Slug Percentage Num of Accounts A a 40% 4 B b 10% 1 C c 50% 5 I was able to get the raw Query but I still need to get the total number of accounts so I can get the percentage I'm struggling with how to do this on ORM. Basically, I did query the categories, joined account categories, and did a distinct on the account so it won't return the duplicates and then just total the result. For the ORM I think I need to filter the account categories to only return the latest account category per account and then total it but I can't seem to write the exact query using ORM I tried using the Subquery and Prefetch but no … -
Save a CSV in a Django FileField through a Django view

Error with Django import-export. | unsupported operand type(s) for +: 'NoneType' and 'datetime.timedelta'
I'm trying to import data with import-export to my model on the admin page. When I do this I get the following error: unsupported operand type(s) for +: 'NoneType' and 'datetime.timedelta' I can trace the error back to my model. See below. It's in the 'def save' part. class MeetingDataLED(models.Model): led_date = models.DateField() led_meeting_date = models.DateField(blank=True) led_start_time = models.TimeField(blank=True) led_type_of_meeting = { ('GBS', 'Special one'), ('KO', 'Special two'), ('NM', 'Special three'), } led_meeting_type = models.CharField(max_length=3, choices=led_type_of_meeting) def save(self, *args, **kwargs): d = timedelta(days=MeetingSetting.objects.get(id=1).meeting_day_led) self.led_meeting_date = self.led_date + d self.led_start_time = MeetingSetting.objects.get(id=1).meeting_time_led super().save(*args, **kwargs) I've read in this post on stackoverlfow that it might have to do with the datetime instance (if I understand it correctly).

Get relative path in Django
I've created a map where I want to implement some kml files into it . If i harcode the url it works but im trying to pass it through a variable because Im dealing with many kml files in a for loop.

Django UserPassesTestMixin raises an unhandled exception

And also, it only uses the permission_denied_message attribute that I set for the exception message and it is not shown to the user. I know that I can override the handle_no_permission method, but is there a better way?

Element not hide when page is reloaded?
I use JQuery formset librairy to manage django inline formsets in my forms. I can add new formset using 'add' button and suppress formset using 'delete' buttons (django-inline-formet). But I have added "lock/unlock" functionality to my forms that disabled all fields when lock button (id = lock) is clicked. So, when form is "locked", fields are disabled and 'add' and 'delete' buttons must also be hidden. I manage to show/hide buttons on lock button click by user. But, when form is locked and page is reloaded by user (F5), 'add' and 'delete' buttons are displayed. It seems that code in function executed with document.ready is not fire. But if I 'manually execute' the code it works. What I have missed? function disabled_field(action) { $('#form').find(':input').not(':button,:hidden').each(function () { if (action == 'locked') { $(this).prop('disabled', true); } else { // only if user has write privilege on form if ($('#is_locked').data('add-privileges') === 'True') { $(this).prop('disabled', false); } } }); } //index of the last empty formset added with 'extra' inlineforsmet parameters var index = formsetnumber() - 1; /* lock a form */ $("body").on("click", '#lock', function (event) { // form is locked => hide inlineformset buttons if ($('#lock').attr('aria-pressed') == 'false') { // hide all formset … -
